The invention discloses biodegradable plastics which is rich in starch and used to produce dining tools and a preparation method thereof; first, the starch is refined, dried and added in silane coupling agent to be mixed evenly at high speed; and then talc and calcium carbonate are respectively added in to be stirred at medium speed; polypropylene is added in to be stirred at medium speed; and processing aid PE wax, plasticizer EVA and antioxidant DLTP are added in to be stirred at low speed; the materials are mixed and stirred in a cold mixing boiler at low speed, and then added into a three-roll sheet machine to produce sheets. The invention solves the problems of the poor interfacial compatibility and the thermo-plastic performance in the prior art, and is characterized in high content of starch, full biodegradation, sanitation and environmental protection.

The invention relates to a speed reducer used for controlling a motor, which comprises an input shaft, a step planetary gear, an internal gear, an output shaft, a right housing, a left housing and a plurality of support bearings. The invention has the advantages that: a high rotational speed meshing is arranged for the gear of the speed reducer, so the processing of the gear is simple with low noise and little heat generating, which is especially obvious with the reducing speed ratio increasing; rolling bearing matching is adopted for the gear and the bearing with high efficiency and convenient installation of the output and the input shafts; 4 to 7 gears participate in meshing work when the gear is meshed with good equal load property, little heat generating, low noise and long service life due to low speed meshing of the gear; four gears can form a speed reducer with less than 100 of drive ratio, thereby adapting to requirement of each sequence reduction ratio and facilitating serial production; reasonable addendum coefficient, modification coefficient and serrated angle of pressure are adopted, thereby achieving a higher transmission efficiency.

The invention provides a suction nozzle for cleaning the road surface, which relates to the field of a road sweeper component. The suction nozzle mainly solves the following problem: under the condition that the air quantity of a blower of a road sweeper is not changed, more than one closed cavity bodies made of soft materials are additionally arranged between an upper cover in the suction nozzle and the road surface so as to exert the function of throttling and press air flow of an air flow channel in the suction nozzle to cling to the road surface for rapid flowing, thereby sucking garbage into a garbage can. Each independently closed soft cavity throttling body is provided with a vent pipe which is connected to a space with the pressure intensity being equal to or higher than that of the air flow at the lower part or is connected with a pressure balancer. The suction nozzle further comprises the upper cover, a peripheral sealant skirt, a framework, supporting road wheels, a traction mechanism, a left air suction pipe orifice, a middle air suction pipe orifice and a right air suction pipe orifice, wherein the left and right air suction pipe orifices move along with a left suction nozzle or a right suction nozzle to extend out of a sweeper body for operation, and can retract to the left and right sides in a middle suction nozzle; each air suction pipe orifice is provided with a large-caliber air flow amplifier, an air back-blowing knife connected with a small-caliber air flow amplifier is respectively arranged at the lower rear part of each air suction pipe orifice, and each air back-blowing knife is matched with the blowing and sucking air flow of the blower on the road sweeper to blow and suck the garbage into the garbage can of the road sweeper.

The invention belongs to the technical field of AGVs and relates to an adjustable-pressure driving mechanism suitable for an AGV. The driving mechanism comprises a pressure adjusting device and a driving device. The pressure adjusting device comprises a linear bearing, a barrel rod, a clamping spring pillar, a bolt, nuts and a support plate frame. The linear bearing is provided with a shaft sleeve fixed under the support plate frame. The clamping spring pillar is sleeved with a spring, and a spring cushion block is arranged at the bottom of the clamping spring pillar. One end of the bolt is connected with a spring adjusting pressing plate and achieves looseness prevention through one nut. The other end of the bolt and the other two nuts press one end of the spring in screwing and combining modes, and deformation quantity of the spring is set. Screwing and combining of the barrel rod and the two round nuts make the spring cushion block fix the other end of the spring. The barrel rod is fixedly connected with a support base in the support plate frame through the clamping spring pillar. The driving mechanism is installed on the AGV so that the bearing limit of the AGV can be changed by adjusting pressure, the bearing range of the AGV is extended, and cost is reduced.

The invention is a piezoelectric driving ultra-precision four-degree-of-freedom positioning and attitude adjusting mechanism and an excitation method thereof. The technical problem that an existing piezoelectric positioning and attitude adjusting mechanism has a single structure, a large size and a high cost of a driving component is solved. The positioning and attitude adjusting mechanism is formed by a mover (1), an upper driving foot (2), a piezoelectric ceramic tube (3), a fixed clamp (4), a lateral guide rail (5), a longitudinal guide rail (6), a lower driving foot (7) and a base (8), wherein the piezoelectric ceramic tube (3) is a main driving element and is used for generating bending deformation to drive the two-degree-of-freedom linear motion and the two-degree-of-freedom rotational motion of the mover (1). Based on the excitation method in the present invention, the positioning and attitude adjusting mechanism can realize large-scale ultra-precision motion. The positioning and attitude adjusting mechanism in the invention has a simple and compact structure, the excitation method is simple and feasible, and the positioning and attitude adjusting mechanism and the excitation method are convenient to apply in the technical field requiring precise positioning and attitude adjustment of an operation object.

The invention discloses a modular construction and assembly method of a boxcar bottom plate. The boxcar bottom plate comprises a floor, a front cross beam, a rear cross beam and side plates. Wherein the two ends of the front cross beam are connected with the two ends of the rear cross beam through side plates respectively, and the tops of the front cross beam, the rear cross beam and the two frames are fixedly connected with the bottom edge of the floor respectively. According to the method, the to-be-produced boxcar bottom plate is formed by combining the pre-produced modules with different sizes, so that the serialization production of the boxcar bottom plates with different sizes is conveniently realized, the mounting process can be simplified, and the production cost is reduced.
